ROSWELL L. PEABODY, OF WALTHAM, MASSACHUSETTS.

STRAIGHT-LINE WATCH.

SPECIFICATION forming part of Letters Patent No. 281,295, dated July 17,1883.

Application filed July 21,1882. (h'o model.)

To all whom it may concern.-

Be it known that I, RoswELL L. PEABonv, of Waltham, county of Middlesex,and State of Massachusetts, have invented certain new and usefulImprovements in Watches, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, andto the letters of, reference marked thereon.

My improvement does not contemplate any new or original parts, but animproved or new plant or arrangement of the parts comprising thelever-escapement. Instead of the straight-line escap ement, (which is inalmost universal use in half-plate, three-quarter plate, and bridgewatches,) I locate the escape-wheel between the fourth wheel and thebalance, thus forming a straight-line watch with this arrangement ofthese three pieces or parts. My object in this arrangement of the partsis to make amore attractive, better, and cheaper watch than can be madewith any model now in use or of which I am aware.

In the accompanying drawings, forming part of this specification, Figurel is a plan or top view of a watch constructed and arranged inaccordance with my invention, and

showing only the parts necessary to an understandlng of my improvements.Fig. 2 is a sectional view upon a plane through line w as of Fig. 1.

In both these figures like letters of reference,wherever they occur,indicate corresponding parts.

A is the pillar-plate or bed of the train, in which the shafts of theseveral wheels are stepped in the usual manner. B is the balance. 0 isthe cock which sustains the balance. D is the cock which sustains theanchor. E is the escape-wheel, and F the fourth wheel.

It will be seen from the drawings that the balance, the escape and thefourth wheels have their axes located in a straight line, (line a: a: ofFig. 1,) and that the anchor-pivot is located at one side of this line,the lines drawn from the pivot to the axes of the escape-wheel andbalance-wheel lying at or nearly at right angles to each other, giving asubstantially right-angled escapement, and this angle may be made acomplete right angle, if desired. Thus I am enabled to produce amovement having all the advantages of the right-angle escapement withthose of the straightline watch. This arrangement of the parts in astraight line, as

explained, affords a ready view of all the parts of the escapement,rendering it easy and convenient to adjust the parts, to assemble anddisassemble them, and to inspect them after they are all united.

The improved arrangement or plant can be manufactured cheaper, moreaccurately and rapidly than the old forms, and can be assent bled withgreater accuracy and rapidity, and thus the total cost to themanufacturer very much diminished.

The arrangement indicated makes an attractive watch-movement, pleasingto'the eye of the ordinary purchaser as well as to the experiencedwatch-maker, and for the general design I propose to make application indue time for a design patent.

I am aware that the form of anchor herein shown is not new; also, thatit has heretofore been proposed 'to locate the pivots of theescape-wheel, balance, and anchor in a straight line; and also to locatethe anchorpivot at one side of the line joining the pivots of thebalance and escape wheels, forming a right-angled escapement. Thesefeatures have been shown in United States Letters Patent, and I do notdesire to be understood as m'akin g any claim to them. My improvementsaccomplish objects, as before set forth, which are not attained by anyof the arrangements heretofore known to me.

Having now fully described my invention, What I claim as new, and desireto secure by Letters Patent, is

In a watch-movement, the combination of the balance, the escape-wheel,and the fourth Y wheel, having their axes located in the same straightline, the anchor escapement sustained by the cock D, and pivoted at oneside of said straight line, as shown, so that the angle between thelines joining said pivot with the axes of the balance and escape wheelshall lie at or nearly at right angles to each other, and the cock 0,the whole being arranged, substantially as shown, so that the palletsare located on one side of the escape- Wheel, and so as to expose allthe parts for convenience of inspection, assembling, and adjustment, forthe purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand inthe presence of two witnesses.

Witnesses:

JOHN BUCKLER, WORTH Osooon.
